SPlNDLE-BEARING FOR SPlNNlNG-FRAMES.

SPECIFICATION formingpart of Letters Patent No. 277,312, dated May 8, 1883.

Application filed May 20, 1882. (No model.)

T 0 all whom 'it may concern Be it known that we, GEORGE B. Mo- GnAcKEN and SAMUEL HAMER, both of Williinantic, in the county of \Vindham and State of Connecticut, have invented a new and useful Improvementin Spindle-Bearings for Spinning-Frames, of which the following is a full, clear, and exact description.

Ourimprovements relate to spindle-bearings ior'spinning-frames; and they consists in certain novel features of construction for insuring the proper supportand lubrication of the spindle, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is an elevation, partly in section, of a spindle, showing our improved means for supporting and lubricating the same. Fig. 2 is a plan view of the tubular bolster-support. Fig. 3 is a longitudinal section of the bolstersupport. Figs. 4 and 5 are sections of the spindle-bolster. Fig. 6 shows a plan and a section of a washer which is used to take the wear.

A is the spindle, provided with an extension-sleeve, B, and whirl D, as usual.

H is a base, of cast-iron provided with a nut, K, for its attachment to the spindle-rail, as usual.

Q is the bolster-support, setting in a recess formed in the upper part of the base H, and

held in place by a cap, F, that is screwedinto the base.

In the hollow stem of the base H is a plunger or stud, I, formed with a point at its upper end for supporting the bolster-support; and J is a spring beneath the plunger I, resting upon a set-screw that is provided with a checknut, B, so that the plunger is sustained.

G is a washer inserted between the bolstersupport Q and the cap F to take up wear between the parts when the spindle and bolstersupport are moved out of a perpendicular position by an unbalanced load. This washer may be elastic or of metal, but it is not essential to the proper workingof the device. When the washer is elastic it will enable the spindle to adjust itself with a great degree of sensitiveness, either under a light or a heavy load.

The bolstersupport Q is formed tubular to receive the bolster O, which is firmly secured in its place by being screwed or driven in. The form or shape of this bolster, as shown most clearly in Figs. 4 and 5, is tubular, with longitudinal ribs on its outer surface extending nearly to its ends; and it will be seen that its ends are shaped so that there are oil-reservoirs P at each end of the bolster, which receive the oil and prevent it from being agitated by the rotation of the spindle. The bolster is provided with notches or holes 0, Fig. 4, at its lower end, to allow the outlet of oil for lubricating the spindle-bearings.

The oiling is accomplished by removing the spindle and inserting a stud in its place, then filling the reservoir, removing the stud, and reinserting the spindle. This may be done without loss of oil. In the working of the spindle the oil will pass down around the out side of the bolster O to the lower reservoir, and thence will work up between the spindle and bolster, so as to lubricate the bearings, the surplus passing over the top of the bolster into the upper reservoir, thus making a continual circulation.

The construction shown and described al-:

lows for the self-adjustment of the spindle to an unbalanced load by a very slight movement. of the parts and with but little wear. It will be seen that a movement of the spindle to one side will force the shoulder of the bolstersupport Q against the washer G and'cap F, and by so doing the plunger I is moved downward and the spring compressed, the parts regaining their normal position as soon as the pressure is removed. The recess in the cap F limits the movement of the bolster-support in a positive manner, even with a very tight band. The spindle being supported near its base, but a small movement will be made with an unbalanced load, and after once being adjusted to the degree of elasticity required the spindle must necessarily remain properly adjusted for a long time, from the fact that the parts have so slight a movement. The point of the plunger I entering the bolster-support retains its central position without regard to wear, and its upward pressure will always be central.

Having thus described our invention, we claim as new and desire to secure by Letters Patent--- l. The combination of the bolster-support Q,
